5-4

Problem

Attempting to scan a document of a size, thickness, or weight that the scanner

cannot scan.

Solution

Check the size, thickness, and weight of the document. For precautions concerning

documents,

see “3-1 Documents,” on p. 3-1

.

Problem

The rollers inside the scanner are dirty or worn.

Solution

Clean the rollers,

see “4-1 Regular Maintenance,” on p. 4-1

. If the rollers are worn,

then they need to be replaced. Contact your local authorized Canon dealer or service

representative to purchase a roller replacement kit.

IMPORTANT

The retard roller and roller unit are consumable components. You need to replace the retard

roller and roller unit when cleaning does not appear to improve performance. Contact your

local authorized Canon dealer or your service representative about purchasing a roller

replacement kit, and then replace the retard roller and the roller unit.

Saved Image Files Do Not Open

When image files saved by CapturePerfect 3.0 cannot be opened by other applications, the

probable causes are as follows.

Symptoms

A multi-page TIFF file saved in CapturePerfect 3.0 cannot be opened by other

applications.

Problem

The application you are using to open the TIFF file does not support multi-page
TIFF files.

Solution

Open the file with an application that supports multi-page TIFF files.

Symptoms

A TIFF file saved in CapturePerfect 3.0 cannot be opened by other

applications.

Problem

If the TIFF file saved in CapturePerfect 3.0 has been compressed, the application
you are using to open the TIFF file does not support the compression type that
was used to save the file in CapturePerfect 3.0.

Solution

Set the compression type for the image file to [None] and save the file again in

CapturePerfect 3.0.

Scanning Results Are Not as Expected

If there is a problem with the scanning result (e.g., the scanned image is not clear, or the image is

striped or dirty,) the probable causes are incorrect ISIS/ TWAIN driver settings or a problem with

the scanning unit inside the scanner. Scanning results can also become skewed if the ISIS/

TWAIN driver has not been installed correctly, or the application in use does not support ISIS/

TWAIN driver functions.

Symptoms

The scanned image is too dark (or faint.)

Problem

The [Brightness] setting is not set to an appropriate value.

Solution

If the image is dark, set a higher [Brightness] setting, or if the image is faint, set a

lower [Brightness] setting.
